Atom-Comments-Feed invalid

[Erunafailaro]

I think, there may be some errors in file /wp-includes/feed-atom-comments.php:

• Line 23: <link rel="alternate" type="<?php bloginfo_rss('html_type'); ?>" content="<?php bloginfo_rss('home'); ?>" /> should be <link rel="alternate" type="<?php bloginfo_rss('html_type'); ?>" href="<?php bloginfo_rss('home'); ?>" />
• Line 43: <link rel="alternate" href="<?php comment_link(); ?>" type="<?php bloginfo_rss('content_type'); ?>" /> should be <link rel="alternate" href="<?php comment_link(); ?>" title="<?php bloginfo_rss('content_type'); ?>" />
• Lines 52 and 53: Dateformat-string is 'D, d M Y H:i:s +0000' but should be 'Y-m-d\TH:i:s\Z', like in line 20, where it is coded correctly.

I think line 43's correct.
